Fix: ERR_SSL_PROTOCOL_ERROR In Chrome Browser

Now, let’s talk about the steps to fix this problem. The first thing we recommend you to do is, check whether the website is no blocked by your ISP. If it’s blocked by the ISP, you won’t be able to access it in any way. The only way left is using a VPN connection.

Check If Website Is Blocked By Your ISP Or Not

Now, open Chrome and enter the website URL. If you’re able to access the website then this means that website is blocked.

Now, you need to use a VPN connection to access that website. You can’t access that website using the regular connection as ISP won’t allow you to do so.

Users who still can’t access the website using the Chrome browser even after using the VPN, then this means there’s something wrong with your system settings or the Chrome browser. Other fixes are given below which will surely fix your problem.

Check Your Internet Date and Time
